I thought I would start one here because there seems to be a bit of interest. There is one on arse which is massive, but full of good info. To get started and your arse on a flight you need a medical, BOSIET & MIST. Differences of opinion on this. Some will say pay for it yourself and others will say the company will pay for it. My company paid for it, but my contract had a clause that I had to pay the cost back if I left before a peroid of time. My thoughts are if you have these ticks in the boxes its one less obstacle. I'm sure someone will be along with a different opinion.
